ARRL 160 CW / ’29 QSO Party

| '29 MOPA |
I spent about five hours last night in the ARRL 160 CW contest, working 321 stations in 74 sections. Conditions were excellent, with my 150W sustaining long runs and big pileups. It reminded me very much of the old F2 days on 6m, running huge pileups of JA's. Unfortunately I'll not be able to continue tonight because of the conflict with the '29 QSO Party.
In reality, I may not be in that one either, as right on schedule the winds have picked up once again, with gusts to 83 km/h predicted throughout the day ... I'll be lucky if the power stays on for the QSO Party tonight. As well as doing their best to blow my antennas around and make my already shaky '29 signal sound even worse, these high winds all too often result in long power outages here in the Southern Gulf Islands ... my fingers are crossed, as they are every year at this time.

If I'm lucky enough to still have power, this will be the inauguration of my newly-constructed MOPA '29 rig ... a two-tube, Master Oscillator Power Amplifier. This rig will be much more 'wind-proof' than my previous mainstays, a single-tube TNT or the Hull Hartley. Both of these self-excited oscillators sound overly 'melodic' when directly coupled to an antenna swinging, or more often, blowing like crazy, in the wind.
If you ever wondered what the ham bands may have sounded like back in 1929, have a listen this Saturday as well as next Saturday night. You will hear some amazingly good signals being generated by these '29 state-of-the-art transmitters as well as some pretty awful sounding ones. It was the pretty awful-sounding ones that led to the crackdown for amateur radio in 1929 as hams were forced to clean up their act or suffer the consequences.
Activity will gather around 3550-3580 kHz and 7100-7125 kHz ... the second weekend will see some meet on the very low end of 160m for an hour, probably around 0400z. I hope some of you will be joining the fun as well, with your newly-constructed 'old' rig!
My New Paddle
I recently received Serial # 20 of the commemorative paddle built for the ARRL by Pietro Begali. As you can see below it is the Begali Sculpture paddle with both the ARRL Logo and the Begali logo. The Serial # is on the bottom.
The key is wonderful and it looks good on the desk. It is still available on the ARRL website.

CW Practice With RufzXP
Lately I've been playing with a very helpful piece of CW-training freeware called 'Rufz', an abbreviation of a German word meaning 'Listening to Callsigns'. Rufz is the brainchild of Mathias Kolpe (DL8MM) and Alessandro Vitiello (IV3XYM).
RufzXP is the latest version, compatible with most operating systems from Windows 98 to Win 8.1.
RufzXP is not a contest simulator with QSB and QRM. The program simply sends 50 calls at random, one at a time, starting at your chosen speed. If you correctly type the call, it will increase speed slightly to send the next call. The speed will continue to increase as long as you correctly copy and type the call ... if not, the speed will decrease to the previous level.
This pattern continues until all 50 calls have been sent. The program then displays all of the calls sent, along with the calls that you typed, as well as the speed. You very soon realize the threshold level between copying comfortably at near 100% and where you start to drop off quickly. It really is a great eye-opener and a wonderful way to increase your copying (and typing) ability.
The highest that I have been able to log a few correct calls is at 54 WPM but I can see that with a few minutes of practice each day, this number should continue to improve. Hopefully my ability to type the calls will also improve as my present keyboarding skills are probably being stifled by my 'hunt and peck' style of typing ... I really should have taken typing in high school and have regretted it ever since.
The website for RufzXP contains a wealth of inspiring data, from sound files of various speeds to lists and photos of various high-speed aficionados ... with an impressively large number being European teenagers. It seems that High Speed Telegraphy World Championships are very popular in Europe and many of the champions are quite young. Have a look at some of the teens, aged 16 or younger (both boys and girls) who are copying over 100 WPM ... several of them not even hams.
A particularly interesting page lets you play the word 'PARIS' at various speeds.
Here it is at 20 WPM:
PLAY
... and again at 50 WPM:
PLAY
... yet again at 100 WPM:
PLAY
Now....listen to 'PARIS' being sent at the present record-holding speed of 200 WPM:
PLAY
I have no idea how anyone could copy CW at this speed but apparently YT7AW was able to correctly copy one call out of seven, sent at this speed ... incredible! Perhaps it is the subconscious mind operating at this level.
You may be interested to see someone copying at just over 140 WPM!
If your CW skills need honing, RufzXP might be just the thing you need.
What is the big deal with amateur radio? What is it that you hear? (Part 1)
Shortwave radio has been a source for great sci-fi plots, spy intrigue novels, movies, and so on, since radio first became a “thing.” But, what is the big deal, really? What is it that amateur radio operators listen to?
In this video, I share some of the types of signals one might hear on the high frequencies (also known as shortwave or HF bands). This is the first video in an on-going series introducing amateur radio to the interested hobbyist, prepper, and informed citizen.
I often am asked by preppers, makers, and other hobbyists, who’ve not yet been introduced to the world of amateur radio and shortwave radio: “Just what do you amateur radio operators hear, on the amateur radio shortwave bands?”
To begin answering that question, I’ve taken a few moments on video, to share from my perspective, a bit about this shortwave radio thing:
Link to video: https://youtu.be/pIVesUzNP2U — please share with your non-ham friends.
From my shortwave website:
Shortwave Radio Listening — listen to the World on a radio, wherever you might be. Shortwave Radio is similar to the local AM Broadcast Band on Mediumwave (MW) that you can hear on a regular “AM Radio” receiver, except that shortwave signals travel globally, depending on the time of day, time of year, and space weather conditions.
The International Shortwave Broadcasters transmit their signals in various bands of shortwave radio spectrum, found in the 2.3 MHz to 30.0 MHz range. You might think that you need expensive equipment to receive these international broadcasts, but you don’t! Unlike new Satellite services, Shortwave Radio (which has been around since the beginning of the radio era) can work anywhere with very affordable radio equipment. All that you need to hear these signals from around the World is a radio which can receive frequencies in the shortwave bands. Such radios can be very affordable. Of course, you get what you pay for; if you find that this hobby sparks your interest, you might consider more advanced radio equipment. But you would be surprised by how much you can hear with entry-level shortwave receivers. (You’ll see some of these radios on this page).
You do not need a special antenna, though the better the antenna used, the better you can hear weaker stations. You can use the telescopic antenna found on many of the portable shortwave radios now available. However, for reception of more exotic international broadcasts, you should attach a length of wire to your radio’s antenna or antenna jack.
The 1929 ‘BK’ QSO Party
The month of December will soon be upon us and that means it's 'BK' time once again! The Bruce Kelley 1929 QSO Party is the annual two-weekend event celebrating the sound of amateur radio as it was in 1929.At no other time of the year can you tune across the bands and hear the melodic sound of radio as it once was ... before the days of crystal-control, when most hams were using self-excited one or two-tube transmitters.
With antennas blowing in the wind, these directly-coupled oscillators often make the band sound like a musical symphony gone wrong ... the wonderful whooping, chirping, buzzing, clicking, drifting, swishing, swaying, warbling, and other interesting sounds of '29, when amateur radio was in its infancy.
If you've ever considered joining-in on the fun, then you still have a few weeks to slap something together for the party ... it need not be 'pretty', but it must be 'compliant'. That is, the tube (or tubes) that you use, must have been available in 1929 or earlier. For receiving, use anything you like ... modern or vintage, as there are no restrictions.
I've penned several blogs on popular circuits and tubes that are commonly used among the BK regulars and they can be viewed here:

Building '29 - What To Build? - PT.1
Building '29 - What To Build? - PT.2
More BK Building
With the usual propagation of early December, it is not surprising that many transcontinental QSO's are made every year, even with the little two or three watters. Considering the 10 watt power input rule, it is surprising how strong some signals from across the country can become on the lower bands, especially on 40m.
Please consider rolling-up your sleeves, heating up your soldering iron and putting something together for the BK fun, especially if you are on the left coast ... and don't be the least concerned about how it looks!
For a gallery of inspiration from individuals that were too weak to resist the temptation, have a look at some previously built '29 time machines.
For the first time, I'll be using my newly constructed MOPA, a two-tuber that will hopefully reduce my annual BK windstorm angst. It seems that every BK weekend, I have gale-force winds here on the island, making my signal a little bit 'too musical', although some '29 diehards still claim to love the sound ... for them, there is no hope.
A semi-annual rant about learning CW
I have been seeing this posted more and more on CW minded Facebook pages:
This is the worst! Yuck! Argh! Ack! Ptooey!
Please take my word for it! As I've told so many times before, I know the frustration of not being able to learn CW. I put off getting my license for at least five years (maybe more), because I could not wrap my brain around the code. And one of the major reasons for that lack of brain wrapping was because someone thought that they were doing me a good turn by handing me a chart similar to the one above.
From personal experience, I can tell you that making the jump from audio input to visual input to brain is the perfect recipe for frustration and resignation. I made the mistake of hearing, trying to visualize and then decode. What you need to do is skip that visual step. Morse Code is a heard language, and unless you're in the Navy operating signal lamps, it's primarily an aural language. To this day, I have extreme difficulty (in fact, I don't even bother) when people "type" out cutsie messages using periods and hyphens to make dits and dahs in print. I have to hear it to de-code. No ifs, ands or buts ..... I have to hear it.
Think about it for a second. When you were a baby, how did you learn to talk - by reading, or by listening to your parents and siblings?
So thanks be to God for the Hams who taught my Novice class. They handed me a set of ARRL Morse Code cassettes with only one word of instruction - LISTEN! And in the end, that's what did it, but the damage had already been done. I had to "unlearn" my past efforts and had to re-learn the direct step of "hear, then de-code". For me, that damage lasted well past 5 WPM. I was stuck at the 10 WPM barrier for a long time, and it was only by the Grace of God that I was able to get up to 13 WPM within 6 months in order to earn my General ticket.
So my advice for those wishing to learn Morse?
1) Ditch any visual aids, as if they were a rattlesnake or the plague.
2) Listen to letters being generated at a speed of anywhere from 13-18 WPM. Let the spacing between the letters determine the code speed. If you listen to Morse being generated slowly and drawn out, you're more than likely going to suffer the 10 WPM plateau like I did.
3) Limit your dedicated practice sessions to no more than 15-20 minutes a pop - two sessions a day, max. At other times, I find it helpful to have Morse playing quietly, almost subliminally in the background while driving, doing chores, etc. IMHO, it gets your brain used to hearing it, and before you know it, you're going to be picking out characters without even realizing it. Lastly, I never liked the concept of listening to random characters once I learned the alphabet. From then on, I found it most useful to listen to actual words and not letter groups. Let's face it, unless you're a spy, you're going to be on the air making conversation - not sending clandestine messages.
4) Once you've learned all the characters and numbers and basic punctuation, and feel somewhat confident in being able to de-code, then get on the air and make QSOs. Real live QSOs are without a doubt, the best vehicle towards increasing your code speed. You can find a lot of beginners hanging out in the 7.120 MHz neighborhood of 40 Meters.
5) Relax, and don't get down on yourself. We all learn things at different speeds. Some people are quick studies and then there are people like me. But if you stick with it, you will get it - I promise.
6) Make full use of W1AW code practice and all the free CW learning software that's out there. Personally, I keep "Morse Trainer" by Wolphi on my phone. It's not a free app, you have to pay for it, but it will generate Morse at speeds up to 60 WPM. I keep it set at 40 WPM. Can I de-code Morse that fast? No way in heck! But I can tell you that after listening (JUST listening - not even trying to decipher) code at that speed for 15 minutes .... code sent at 25 or 28 WPM sounds a lot slower than it used to.
I suffered the double whammy. I had to "unlearn" the aural to visual to brain process; and then once I actually learned the code, I had to unlearn the "code letters sent at 5 WPM" error. Look at me now - CW is my most preferred mode and I am comfortable anywhere around the 25 WPM mark! On a good day, if I don't tense up, I can go for short bursts of 30 -35 WPM. The bottom line is, that learning and becoming proficient with Morse Code is not impossible, in most cases.
Take it from someone who thought it was.
